Four-point Angular Contact Ball BearingsQJ222N2MA Bearing

Four-point Angular Contact Ball Bearings are a type of ball bearings that are designed to handle high radial and axial loads in both directions. These bearings feature four contact points between the inner and outer rings, providing increased rigidity and greater load capacity compared to other types of bearings.

With their unique design, four-point angular contact ball bearings are ideal for applications where space is limited and high precision is required. This type of bearing is commonly used in applications such as robotics, machine tools, and heavy machinery.

One of the key benefits of utilizing four-point angular contact ball bearings is their ability to handle both radial and axial loads simultaneously. This makes them an ideal choice for applications where both types of loads are present. Additionally, their enhanced load-bearing capacity allows for higher performance and longer lifespan, which results in lower maintenance costs and downtime.


Four-point angular contact ball bearings QJ222N2MA are designed to handle both radial and axial loads in a single bearing. These bearings are constructed with four points of contact that allow for higher load capacity and improved stability. The QJ222N2MA model has a bore diameter of 110mm, an outer diameter of 200mm, and a width of 38mm. 

These bearings come with a brass cage that enhances durability and reduces friction, allowing for efficient operation at high speeds. In addition, the cage is designed to prevent the bearing balls from rubbing against each other, which can cause premature wear and failure. 

QJ222N2MA bearings are suitable for use in a wide range of applications, including machine tools, robotics, and construction equipment. They are known for their high performance and long service life, making them a cost-effective solution for many industries. 

At our company, we offer a variety of customization options to meet the specific needs of our customers. These options include different cage materials, greases, and coatings, allowing us to provide a bearing solution tailored to each individual application. 

In conclusion, if you are looking for a reliable and efficient solution for your bearing needs, consider using QJ222N2MA four-point angular contact ball bearings. Contact us today to discuss your requirements and learn more about our range of bearing products.
